Description

Technical Field

[0001] This invention relates to the field of optical fiber cable processing and manufacturing technology, and in particular to a connector for optical fiber cable processing. Background Technology

[0002] In the processing of optical fiber cables, such as stripping, cutting and grinding, clamping sockets are required to strictly position and hold the cables. Stable and non-destructive mechanical fixation is the basic prerequisite for ensuring the processing accuracy of optical fibers, reducing signal loss and avoiding microcracks in the fiber core, which directly affects the processing efficiency of the production line and the final product quality.

[0003] Taking the Chinese patent with authorization announcement number CN221507194U as an example, the technology discloses a device for manufacturing optical fiber connectors, the structure of which clearly includes an optical fiber clamp; the clamp mainly consists of a base at the bottom and a clamping claw at the top that cooperates with it, and relies on the mechanical displacement and pressing of the base to achieve the clamping and positioning of the optical fiber cable.

[0004] The existing technology has the following physical structural defects: First, the grippers lack flexible buffering when pressing down, and the hard contact can easily cause mechanical crushing damage to the fragile optical fiber; second, the positioning slots are mostly single fixed structures, which cannot adapt to and be compatible with cables of different outer diameters, resulting in cumbersome cable replacement operations; finally, the debris generated during processing is very easy to fall off and accumulate in the dead corners of the positioning slots for a long time. Due to the lack of a smooth physical chip removal channel, the accumulation of debris will directly lead to poor coaxiality of subsequent optical fiber placement and positioning failure. Summary of the Invention

[0005] Technical problems to be solved To address the physical structural defects of existing technologies, such as rigid grippers causing mechanical crushing damage to fragile optical fibers, the inability of a single fixed slot to adapt to and accommodate cables of different outer diameters leading to cumbersome cable replacement, and the accumulation of processing debris in dead corners of the positioning slot lacking a smooth physical chip removal channel, resulting in positioning failure, this invention provides a clamping connector for optical fiber cable processing. This invention aims to achieve high-precision, non-destructive adaptive clamping of multi-specification optical fiber cables through a linkage and combination structure, and to construct an efficient gravity and pneumatic chip removal channel to ensure the continuity and stability of high-frequency assembly line processing.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A fiber optic cable processing connector includes: a base with a chip collection cavity for collecting processing debris; a U-groove module fixedly disposed on the top surface of the base for placing fiber optic cables, with the bottom end of the U-groove module communicating with the chip collection cavity; a locking mechanism installed on one side of the base; and a positioning connector module connected to the execution end of the locking mechanism and suspended directly above the U-groove module; wherein the locking mechanism is a lever mechanism configured to drive the positioning connector module to move downwards to press and fix the fiber optic cable within the U-groove module.

[0007] Preferably, the U-groove module extends in a stepped manner along the placement axis of the optical fiber cable, with a first diameter groove segment, a second diameter groove segment, and a third diameter groove segment; the groove width and groove depth of the first diameter groove segment, the second diameter groove segment, and the third diameter groove segment decrease sequentially to mechanically adapt to optical fiber cables of different diameter specifications.

[0008] Preferably, the bottom surface of the chip collection chamber is inclined to form a gravity chip removal ramp; the base is located on the lower end of the gravity chip removal ramp and is fitted with a collection box via a pull-out plug-in connection.

[0009] Preferably, an air blowing nozzle is installed through the outer wall of the base on the upper inclined side corresponding to the highest point of the gravity chip removal slope; the air blowing direction of the air blowing nozzle is along the inclined direction of the gravity chip removal slope and directly faces the opening side of the collection box.

[0010] Preferably, the collection box has a filter window on the end panel exposed on the outside of the base, the filter window being used to block and collect solid debris as airflow passes through.

[0011] Preferably, the locking mechanism includes: a triangular support fixedly supported on the side of the base; an ear plate connecting seat fixedly installed on the top plane of the triangular support; a U-shaped right-angle pressure rod hinged to the ear plate connecting seat by a pin in the middle, the front end of the U-shaped right-angle pressure rod extending horizontally and used to install the positioning and locking module; and a V-shaped handle and a transmission link, the V-shaped handle being hinged to the tail of the U-shaped right-angle pressure rod and the transmission link, together forming a quick clamping linkage mechanism that can achieve mechanical self-locking by pressing down past the dead point.

[0012] Preferably, a strip-shaped through groove is provided on the front horizontal surface of the U-shaped right-angle pressure bar, and the positioning and snapping module includes a bolt rod that is vertically inserted into the strip-shaped through groove; the bolt rod is limited and fixed by screwing it onto its body and pressing against the nuts and pressure washers on the top and bottom sides of the U-shaped right-angle pressure bar, and its longitudinal height can be adjusted by rotating the nuts.

[0013] Preferably, the positioning and snapping module further includes a flexible contact pad movably sleeved on the bottom of the bolt member, the bottom surface of the flexible contact pad being arc-shaped to conform to the surface of the optical fiber; a spring member is linked between the flexible contact pad and the bolt member to provide physical flexible buffering force for the downward pressing action.

[0014] Preferably, an outer edge piece is fixedly extended outward on the outer wall of the lower part of the bolt member, and a flange piece is fixedly provided on the bottommost end face of the bolt member; a guide groove is formed downward from the center of the top surface of the flexible contact pad; the flange piece is slidably inserted and confined within the guide groove; the spring member is spirally sleeved on the lower end of the bolt member, and the upper and lower ends of the spring member respectively abut against the bottom surface of the outer edge piece and the top surface of the flexible contact pad.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a spring component in the positioning and locking module that works in conjunction with a flexible contact pad to provide a flexible buffering force when the locking mechanism is pressed down. This structure avoids the mechanical damage caused by the direct squeezing of the optical fiber by traditional rigid grippers, and can protect the integrity of the fragile optical fiber structure while ensuring effective clamping.

[0016] The U-groove module of the present invention has a first diameter groove segment, a second diameter groove segment, and a third diameter groove segment arranged along the optical fiber placement axis, so as to realize the sequential decrease of the groove width and depth. This stepped structure enables the same card socket to be physically compatible with the stable placement of different size segments of optical fiber outer sheath, tight-buffered fiber to bare fiber, etc., reducing the cable replacement process when switching cable specifications and improving the continuity of assembly line processing.

[0017] This invention connects the bottom of the U-groove module to the chip collection cavity inside the base, and, in conjunction with a gravity chip removal ramp, an air blowing nozzle, and a collection box with a filter window, constructs a smooth physical chip removal channel. The chips generated during processing can fall directly, slide down the ramp, and be concentrated in the collection box under the action of auxiliary airflow, avoiding the accumulation of chips in the dead corners of the positioning groove, and ensuring the coaxiality of the optical fiber placement and the positioning accuracy of long-term processing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Please see Figures 1-7 The present invention provides a connector for processing optical fiber cables, which is mainly composed of structural components such as a base 1, a U-groove module 2, a locking mechanism 3, and a positioning connector module 4.

[0023] Regarding the embodiment of the chip removal and guiding support structure: The base 1 serves as a basic support component, and its interior is hollowed out to create a chip collection cavity 5 for collecting chips from fiber optic stripping or cutting processes. The U-groove module 2 is fixedly mounted on the top surface of the base 1 to stably place the fiber optic cable. To solve the chip accumulation problem, the deepest part of the bottom of the U-groove module 2 is not closed, meaning that the bottom end of the U-groove module 2 is directly connected to the chip collection cavity 5 below, allowing chips on the working surface to fall naturally into the chip collection cavity 5 under gravity.

[0024] Furthermore, the bottom surface of the chip collection chamber 5 is inclined, forming a gravity chip removal ramp 7. The inclination angle of the ramp promotes the downward sliding of debris. The base 1 is located on the lower end of the gravity chip removal ramp 7, and a collection box 6 is installed via a pull-out plug-in connection. On the outer wall of the base 1, on the upper inclined side corresponding to the highest point of the gravity chip removal ramp 7, an air blowing nozzle 8 for connecting to an external compressed air source is installed. The air blowing direction of the air blowing nozzle 8 follows the inclination direction of the gravity chip removal ramp 7, directly facing the opening side of the collection box 6. To prevent debris from splashing out of the collection box during air blowing, a filter window 9 is provided on the end panel of the collection box 6 exposed on the outer side of the base 1. The filter window 9 allows airflow to pass through, but effectively blocks and collects solid debris.

[0025] To address compatibility issues with optical fibers of different diameters, the U-groove module 2 extends in a stepped manner along the placement axis of the optical fiber cable, comprising a first diameter groove segment 21, a second diameter groove segment 22, and a third diameter groove segment 23. The groove width and depth of the first diameter groove segment 21, the second diameter groove segment 22, and the third diameter groove segment 23 decrease sequentially. In practical applications, the first diameter groove segment 21 is used to clamp the coarse outer sheath of the optical fiber, the second diameter groove segment 22 clamps the tightly sheathed portion, and the third diameter groove segment 23 clamps the thin bare fiber portion, achieving purely physical step-adaptive design.

[0026] Regarding the embodiment of the clamping and flexible buffer structure: The locking mechanism 3 is installed on one side of the base 1 and is a type of quick clamping linkage mechanism. Specifically, the locking mechanism 3 includes a triangular support 31 fixedly supported on the side of the base 1, and an ear plate connecting seat 32 fixedly installed on the top plane of the triangular support 31. The middle part of the U-shaped right-angle pressure rod 33 is hinged to the ear plate connecting seat 32 by a pin, and its front end extends horizontally to the top of the U-groove module 2 for installing the positioning and snap-fit ​​module 4. The V-shaped handle 34 is hinged to the tail of the U-shaped right-angle pressure rod 33 and the transmission linkage 35. When the operator presses down on the V-shaped handle 34, the linkage mechanism is mechanically linked, driving the front end of the U-shaped right-angle pressure rod 33 to press down and achieve mechanical self-locking after passing the mechanical dead point, maintaining a stable clamping state.

[0027] To avoid damage to the optical fiber from rigid downward pressure, a strip-shaped through groove is provided on the horizontal surface of the front end of the U-shaped right-angle pressure rod 33. The positioning and snap-fit ​​module 4 includes a bolt member 41 that is vertically inserted into the strip-shaped through groove. The bolt member 41 is fixed in place by two nuts 42 screwed onto its body, which, in conjunction with pressure washers 43 on the upper and lower sides of the U-shaped right-angle pressure rod 33, provide limiting and fixing. Workers can physically adjust the longitudinal suspension height of the bolt member 41 by loosening and tightening the nuts 42.

[0028] A flexible contact pad 44 is movably connected to the bottom end of the bolt member 41. The bottom surface of the flexible contact pad 44 is arc-shaped, which can conform to the cylindrical surface of the optical fiber cable to the maximum extent and disperse local stress. The specific connection relationship is as follows: an outer edge piece 45 is fixedly extended outward on the outer wall of the lower part of the bolt member 41, and a flange piece 48 is fixedly provided on the bottom end face of the bolt member 41. A guide groove 47 is opened downward from the center of the top surface of the flexible contact pad 44. During assembly, the flange piece 48 slides into and is confined within the guide groove 47, so that the flexible contact pad 44 can produce limited vertical displacement along the bolt member 41. At the same time, the spring member 46 is spirally sleeved on the outside of the lower end of the bolt member 41, with its upper end abutting against the bottom surface of the outer edge piece 45 and its lower end abutting against the top surface of the flexible contact pad 44.

[0029] The working principle and usage process of this invention are as follows: During processing preparation, the worker lifts the V-shaped handle 34 upwards, causing the front end of the U-shaped right-angle pressure rod 33 to tilt upwards, and the positioning and locking module 4 to leave the U-groove module 2. The worker places the optical fiber cable to be processed flat into the U-groove module 2, so that different diameter sections of the cable fall into the corresponding first diameter groove section 21, second diameter groove section 22, and third diameter groove section 23, respectively. Subsequently, the worker presses down the V-shaped handle 34 with one hand, and the linkage mechanism self-locks at the dead point, causing the U-shaped right-angle pressure rod 33 to drive the bolt rod 41 to move downwards. The flexible contact pad 44 first contacts the surface of the optical fiber. As the U-shaped right-angle pressure rod 33 continues to press down a small distance, the flexible contact pad 44 floats upwards along the guide groove 47, pressing the spring member 46 upwards. The spring member 46 deforms under pressure, converting the rigid mechanical downward pressure into a flexible buffer clamping force, firmly confining the optical fiber within the U-groove. During wire stripping or cutting, the generated debris falls from the connection at the bottom of the U-groove module 2 into the chip collection chamber 5, and then onto the gravity chip removal ramp 7. An external air source injects airflow into the chip collection chamber 5 through the air blower nozzle 8, blowing the debris down the ramp into the collection box 6. The airflow is then discharged through the filter window 9, maintaining absolute cleanliness within the positioning groove. After processing is complete, the V-shaped handle 34 is lifted in the opposite direction to instantly release the lock and remove the optical fiber.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
